Technical field

The utility model relates to the propelling unit field of propulsive fluid acting, specifically a kind of deep water oar blade type propelling unit.

Background technology

Being used at present the device of propulsive fluid acting mainly is the oar blade type propelling units such as the screw propeller that uses of various naval vessels and helicopter and reciprocal blade, the crank-driven that screw propeller drives by engine piston connecting rod, and degradation of energy is large, effective power is low; Present oar blade type propelling unit must some could be worked more than the water surface, comformability is not high, and only have in the process that blade rotates a circle part time can provide forward thrust, part time can produce resistance by convection cell, the faster resistance of rotative speed is larger, this type of propelling unit manufacturing process is complicated, and cost is higher.

Along with making constant progress of science and technology, the quickening of the large tonization of boats and ships, deep water paces, excavate marine resources become countries in the world in the urgent need to, there are the weak points such as energy consumption is large, efficient is low in the spiral propeller that generally uses on the existing various ships.

The utility model content

The shortcomings such as the liquid propeller degradation of energy is large in the prior art, effective power is low, using adaptability is not high in order to solve, and the manufacturing process complexity, and cost is lower, the utility model provides a kind of deep water oar blade type propelling unit.

The technical scheme that the utility model addresses the above problem is:

A kind of deep water oar blade type propelling unit, comprise blade, oar handle and rotating shaft, rotating shaft is connected with propulsion source, one end of oar handle is connected with blade, the other end is installed in the rotating shaft, but oar handle moves in a circle and rotation with rotating shaft, also comprises gear and disk, and described disk is fixed on the propelling unit casing, the through hole of disc centre is passed in rotating shaft, disc face is parallel with oar handle, and disk is provided with the slideway of annular, and described gear is fixed on the oar handle, and move in a circle along slideway with oar handle, be provided with two groups of rach slots and tooth bar in the slideway, tooth bar is arranged in the rach slot, and the number of teeth of tooth bar is 1/4th of the gear number of teeth.

Described two groups of tooth bars arrange along be separated by 90 ° of angles of the slideway of annular.

Described oar handle and blade respectively are provided with four, between adjacent two oar handles at an angle of 90.

Be provided with the connecting bore that is connected with oar handle in rotating shaft, the cross-sectional plane that rotating shaft is positioned at the part of connecting bore is quadrangle, and each limit becomes camber line, and the connecting bore inwall is provided with the elastic telescopic ball, and elastic telescopic ball and oar handle are tangent.

Produce a pair of application force and antagonistic force when blade is done gyroscopic movement and between the fluid, fluid advances to the antagonistic force promotion machine of blade, but in the process that blade rotates a circle, only have part time can provide forward thrust, the present invention becomes blade design and self also can rotate in the process that moves in a circle along rotating shaft, and the blade automatic rotation provides thrust to driving surface (contacting with large tracts of land between the working direction fluid) when oar can propelling fluid be done positive work and promoted machine and advance; Will automatic rotation when turning over the certain angle blade and can not provide again the power that advances to non-working surface (contacting with small size between the working direction fluid), in the process of this cyclic switching blade driving surface, provide lasting propelling thrust for machine;

In the operation process, rotating shaft provides the power of oar rotation, rotates by finishing self with the engagement of slideway middle rack when gear slides in slideway, thereby drives self rotating of blade.

The beneficial effects of the utility model are:

(1) in the utility model blade be designed to can be in the process that moves in a circle the direction of self relative fluid be variable, in the process of this cyclic switching blade driving surface, provide lasting propelling thrust for machine, reduce the propelling unit degradation of energy, improved efficient;

(2) the utility model can use in deep water, strong adaptability;

(3) the utility model is simple in structure, and manufacturing cost is lower.

The specific embodiment

Below in conjunction with the specific embodiment, the utility model is further elaborated.

As shown in the figure, a kind of deep water oar blade type propelling unit, comprise blade 1, oar handle 2 and rotating shaft 4, rotating shaft 4 is connected with propulsion source, one end of oar handle 2 is connected with blade 1, the other end is installed in the rotating shaft 4, is provided with the connecting bore that is connected with oar handle 2 in rotating shaft 4, and the cross-sectional plane that rotating shaft 4 is positioned at the part of connecting bore is quadrangle, each limit becomes camber line, the connecting bore inwall is provided with elastic telescopic ball 9, and elastic telescopic ball 9 is tangent with oar handle 2, but oar handle 2 moves in a circle and rotation with rotating shaft 4, oar handle 2 and blade 1 respectively are provided with four, at an angle of 90, also comprise gear 3 and disk 5 between adjacent two oar handles 2, described disk 5 is fixed on the propelling unit casing, the through hole at disk 5 centers is passed in rotating shaft 4,5 in disk is parallel with oar handle 2, and disk 5 is provided with the slideway 6 of annular, and described gear 3 is fixed on the oar handle 2, and move in a circle along slideway 6 with oar handle 2, be provided with 8, two groups of tooth bars of two groups of rach slots 7 and tooth bar 8 in the slideway 6 and arrange along the slideway 6 of the annular 90 ° of angles that are separated by, the number of teeth of tooth bar 8 is 1/4th of gear 3 numbers of teeth;

As shown in Figure 2, the figure cathetus direction of arrow is working direction, the camber line direction of arrow is that oar handle 2 is along rotating shaft 4 rotation directions, blade 1 is below moving to horizon 45 ° the time, be fixed on gear 3 on the oar handle 2 and meet tooth bar 8 and rach slot 7 in the slideway 6, gear 3 makes oar handle 2 that autobiography occur with the engagement of tooth bar 8, from but blade 1 conversion direction, this moment, blade 1 was perpendicular along the plane that rotating shaft is rotated with oar handle 2, fluid advances to the antagonistic force promotion machine of blade 1, because antagonistic force provides forward thrust to diminish gradually, raise the efficiency in order to save energy when so turning over 90 °, blade 1 is shifted one's position again, the plane parallel that this moment, blade 1 and oar handle 2 rotated along rotating shaft, reduce with the interaction of fluid, until forward horizon 45 ° of again dislocations of position in below to, so circulation goes down to provide propulsive effort;

Gear 3 reaches with engagement process such as Fig. 6 of slideway middle rack 8 extremely shown in Figure 8 in slideway, the number of teeth of tooth bar 8 is 1/4th of gear 3 numbers of teeth, when gear 3 moves to tooth bar 8 position, under the engagement of gear 3 and tooth bar 8, gear 3 self half-twist, thus drive blade 1 half-twist on the oar handle 2, such as Fig. 6 to shown in Figure 8, in this process, the A point on the gear self half-twist; When gear 3 is not met tooth bar 8, as shown in Figure 5, because gear 3 is in the state of fitting tightly with slideway 6, and the elastic telescopic ball 9 of oar handle 2 and rotating shaft 4 junctions makes oar handle 2 fixing, as shown in Figure 4, therefore self rotation can not occur in gear 3, thereby blade 1 direction is immobilized, such as Fig. 5 to Fig. 6, in the gear movement process, self does not rotate gear, A point invariant position among the figure;

As shown in Figure 3, every blade 1 of 90 ° of configurations, to guarantee the continuity of the power that propelling unit was provided, machine is steadily advanced.
